handle labels with 8-bit byte values in dn_skipname
The original logic considered each byte until it either found a 0
value or a value >= 192. This means if a string segment contained any
byte >= 192 it was interepretted as a compressed segment marker even
if it wasn't in a position where it should be interpretted as such.
The fix is to adjust dn_skipname to increment by each segments size
rather than look at each character. This avoids misinterpretting
string segment characters by not considering those bytes.
